Fabricate Client

The official Fabricate client package for Python.

Installation

pip install tonic-fabricate

Usage

To generate and download data from Fabricate:

from tonic_fabricate import generate

generate(
    # The workspace to use
    workspace='Default',

    # The name of the database to generate
    database='ecommerce',

    # The format to generate. Should be one of:
    # - 'sql'
    # - 'sqlite'
    # - 'csv'
    # - 'jsonl'
    # - 'xml'
    format='sql',

    # The destination to save the data
    dest='./data',

    # Optional: Overwrite the destination if it exists
    overwrite=True,

    # Optional: Generate a single table
    # entity='Customers',
)

To push data to an existing database:

from tonic_fabricate import generate
import os

generate(
    # The workspace to use
    workspace='Default',

    # The name of the database in Fabricate
    database='ecommerce',

    # The connection details for the target database
    connection={
        # The host of the target database
        'host': 'host.example.com',

        # The port of the target database
        'port': 5432,

        # The name of the target database
        'database_name': 'ecommerce',

        # The username for the target database
        'username': os.environ.get('FABRICATE_DATABASE_USERNAME'),

        # The password for the target database
        'password': os.environ.get('FABRICATE_DATABASE_PASSWORD'),

        # Whether to use TLS for the connection
        'tls': True,
    },
)

Progress Tracking

You can track the progress of data generation using a callback function:

from tonic_fabricate import generate

def on_progress(data):
    phase = data.get('phase', '')
    percent = data.get('percentComplete', 0)
    status = data.get('status', '')

    phase_text = f"[{phase}] " if phase else ""
    status_text = f", {status}" if status else ""
    print(f"{phase_text}{percent}% complete{status_text}...")

generate(
    workspace='Default',
    database='ecommerce',
    format='sql',
    dest='./data',
    on_progress=on_progress
)

Environment Variables

The client will automatically use the following environment variables if they are set:

• FABRICATE_API_KEY: Your Fabricate API key
• FABRICATE_API_URL: The Fabricate API URL (defaults to https://fabricate.tonic.ai/api/v1)

Error Handling

The client raises appropriate exceptions for various error conditions:

from tonic_fabricate import generate

try:
    generate(
        workspace='Default',
        database='ecommerce',
        format='sql',
        dest='./data'
    )
except ValueError as e:
    print(f"Invalid parameters: {e}")
except Exception as e:
    print(f"Generation failed: {e}")
